Deadly DDoSer Virus

Hello everybody! I have a virus that disabled my task manager and my registry editing, and when I use my antivirus it says that there are unknown files in my Local Settings folder, and when I looked into it, my Local Settings folder is gone .-. The virus also disables my firewall upon start up, and I have to restart my firewall every time I log in. I have the link where I got the virus if that helps. Many thanks!
